In the display example, RUD (Rudder) is set to REVERSE.
Fail Safe and Hold General Instructions Fail Safe • F/S or HOLD can be selected for each channel (1 to 8). • Channels selected for HOLD will remain in HOLD until a normal signal resumes. Those selected for F/S will move to their pre-set positions after 1 second of signal interruption. • F/S SET simultaneously stores the desired Fail Safe position in the transmitter memory and sends it to the receiver.
ADJUSTMENTS AND FLIGHT TECHNIQUES ADJUSTABLE TRAVEL VOLUME • The ATV function is used to adjust servo travel limits. Servo travel can be adjusted independently in each direction from neutral. Adjustment from 30% to 110% of normal full travel (throw) is possible. • NOTE: When servo travel is changed by ATV, the limits of trim throw and the Dual Rate ON (Low Rate) limits are increased or reduced by the same percentage. • ATV limits are displayed by a bar graph and numbers.
ADJUSTABLE FUNCTION RATE AFR is a servo endpoint limiting function, similar to ATV with three exception: trol response without the necessity of going through the usual programming steps. Adjustments can even be made during flight (by an assistant). Maximum adjustment available on the sub trimmers is ±25% of the amount of travel set on the AFR program screen. Setting Method 1) The setting method for AFR is the same as for ATV (See page 16). 2) Select the EDIT screen and press the AFR program key.
ADJUSTMENTS AND FLIGHT TECHNIQUES DUAL RATE Dual Rate functions allow the modeler to switch servo travel limits in flight, thus varying the control sensitivity for different flight conditions or maneuvers. • Dual Rate functions are available on CH1 (Aileron), CH2 (Elevator), and CH4 (Rudder). • Dual Rate ON (Low Rate) limits can be adjusted from 30% to 100% of full throw. • If servo travel is reduced by ATV, the D/R ON throw will be 30% to 100% of the limit set by ATV (in D/R OFF).
Auto Dual Rate • Dual Rate functions may be switched ON and OFF automatically, according to the Throttle (CH3) control stick position. 1) Move the cursor to the "mode" position with the or cursor key. cursor key to select the 2) Use the or D/R function to be set to AUTO and press the program key. 3) Use the and cursor keys- to move the cursor to "pos". 4) Set the Throttle stick at the point you wish ON/OFF switching to occur, and press the program key.
ADJUSTMENTS AND FLIGHT TECHNIQUES Select the EDIT screen, and move the cursor to Line 2 with the Exponential Mixing Trim Parameter Model » or t cursor key. End EXPONENTIAL/VTR Exponential or VTR functions can be used to change the servo response curve from the normal linear operation. This can be very helpful if control response is either sluggish or too sensitive near the neutral position. Maximum servo deflection limits (set by ATV and/or A FR) remain the same.
TYPE 1 Positive With this type of curve, control response will be made more sensitive near neutral and less sensitive as the stick is deflected farther towards its extreme limits. TYPE 1 Negative With this type of curve, control response wilt be "softer" around neutral and increase as the stick is deflected farther. TYPE 2 Positive With this type of curve, response will be most sensitive at the LOW end of control stick travel, and decrease as the stick is moved toward HIGH.
ADJUSTMENTS AND FLIGHT TECHNIQUES MIXING • Mixing allows two or more channels to be controlled by a single transmitter control stick or lever. This set features Programmable Mixing with four independent mixing circuits, along with special built-in mixing circuits. • NOTE: Only PROG-MIX Programmable Mixing can be used in the BASIC Parameter mode. (See PARAMETER, page 43). There are six types of mixing (including Prog. Mixing).
PROGRAMABLE MIX Programmable Mixing Four separate Programmable Mixing circuits allow almost infinite mixing combinations. The features of this program provide the modeler with unlimited versatility in trimming and control ing complex, high-performance models. • • • • Mixing of any two channels is possible.
